List of flexors of the human body

A flexor is a muscle that flexes a joint. In anatomy, flexion (from the Latin verb flectere, to bend) is a joint movement that decreases the angle between the bones that converge at the joint. For example, one's elbow joint flexes when one brings their hand closer to the shoulder. Flexion is typically instigated by muscle contraction of a flexor. of the humerus bone (the bone in the upper arm) at the shoulder Pectoralis major Anterior deltoid Coracobrachialis Biceps brachii of the forearm at the elbow Brachialis Brachioradialis Biceps brachii of carpus (the carpal bones) at the wrist flexor carpi radialis flexor carpi ulnaris palmaris longus of the hand flexor pollicis longus muscle flexor pollicis brevis muscle flexor digitorum profundus muscle flexor digitorum superficialis muscle The hip flexors are (in descending order of importance to the action of flexing the hip joint): Collectively known as the iliopsoas or inner hip muscles: Psoas major Iliacus muscle Anterior compartment of thigh Rectus femoris (part of the quadriceps muscle group) Sartorius One of the gluteal muscles: Tensor fasciae latae Medial compartment of thigh Pectineus Adductor longus Adductor brevis Gracilis Without the iliopsoas muscles, flexion in sitting position is not possible across the horizontal plane.
